alpha: Define ioremap_wc

groeck · mattst88 · commit 7817cedce043 · 2017-08-29T12:01:57.000-07:00
Commit 3cc2dac ("drivers/video/fbdev/atyfb: Replace MTRR UC hole with strong UC") introduces calls to ioremap_wc and ioremap_uc. This causes build failures with alpha:allmodconfig. Map the missing functions to ioremap_nocache. Fixes: 3cc2dac ("drivers/video/fbdev/atyfb: Replace MTRR UC hole with strong UC") Cc: Paul Gortmaker <paul.gortmaker@windriver.com> Cc: Luis R.
